Abstract (en)
[origin: WO0023936A1] One aspect of the present invention is a method and apparatus of providing a card (30) and/or reader (20) that recognizes a communication mode of a corresponding reader (20) and/or card (30). The card (30) reader (20) comprises a memory (42) and a card (30) interface circuit (44) to detect a mode of a card (30). A processor (40) coupled to the card (30) interface circuit (44) and the memory (42), communicates with the card (30) in the detected mode if the detected mode matches a communication mode of the processor (40). The card (30) comprises a memory (34) and a reader interface circuit (36) to detect a mode of a reader (20). A processor (32) coupled to the reader (20) interface circuit (36) and the memory (34), communicates with the reader (20) in the detected mode if the detected mode matches a communication mode of the processor (32). Another aspect of the present invention is a method and apparatus of providing a card and/or reader that is operable in two communication modes. The dual mode card reader comprises a memory and a card interface circuit to detect a mode of a card, the mode being one of first and second communication modes. A processor coupled to the card interface circuit and the memory, communicates with the card in the detected mode. The dual mode card comprises a memory and a reader interface circuit to detect a mode of a reader, the mode being one of first and second communication modes. A processor coupled to the card interface circuit and the memory, communicates with the reader in the detected mode.
